Separateprovisions spell out the requirements forwindows and doors used for emergency escapeand rescue.2015 IRC Transition from the 2009 IRCR310.2.2Window Well Drainage2015 IRC Transition from the 2009 IRC43R310.5, R310.6 Emergency Escape2015and Rescue Openings for Additions,Alterations and Repairs The basement of a dwelling addition does notrequire an emergency escape and rescueopening if there is access to a basement thatdoes have an emergency escape and rescueopening.

2015 IRC Transition from the 2009 IRCR311.7.3, R311.7.5.1Stair Risers2015 The total vertical rise in a stairway without anintermediate landing has increased from 144into 147 in. The provision for allowing open risershas been clarified. It is based on the distanceabove grade or the floor below, not on the totalrise of the stair. A new exception clarifies thatopen risers are permitted on spiral stairways.2015 IRC Transition from the 2009 IRCR311.7.6Landing for StairwaysCopyright 2015 International Code Council2015 The code adds a definition of spiral stairway thatomits any requirement for a center post to allowfor design flexibility. The code now limits the sizeof spiral stairways by restricting the radius at thewalk line to a dimension not greater than 24 ½ins. The method of measurement for tread depthnow matches the winder provisions andmeasures at the intersection of the walk line andthe tread nosing rather than perpendicular to theleading edge of the tread.452015 For a turn in a stairway, the IRC now specificallypermits angular and curved stair landing withcertain dimensions less than 36 inches if theprescribed depth is provided at the walk line andminimum area criteria are satisfied. Themaximum vertical rise requirement of 12 feet hasbeen moved from the exception to a newSection R311.7.3.2015 IRC Transition from the 2009 IRCR311.7.10.1Spiral Stairways462015 IRC Transition from the 2009 IRCR311.7.11, R311.7.12 AlternatingTread Devices and Ship Ladders472015 Alternating tread devices and ship ladders havebeen added to the stair provisions.

Theinterconnection provisions havebeen moved out of the sectionsrelated to location and powersource and placed in a newsection.Battery-operated smoke alarmsare permitted for satisfying thesmoke alarm power requirementswhen alternations, repairs, andadditions occur.

Exterior work such asroofing, sliding, windows, doors, and decksand porch additions no longer trigger thecarbon monoxide alarm provisions forexisting buildings. An attached garage isone criterion for requiring carbonmonoxide alarms, but only if the garagehas an opening into the dwelling. A carbonmonoxide alarm is required in bedroomswhen there is a fuel-fired appliance in thebedroom and adjoining bathroom. CarbonMonoxide detection systems only requiredetectors installed in the locationsprescribed by the code and not those53locations described in NFPA 720.2015 IRC Transition from the 2009 IRC2012 IRCR316.4Reference to a newstandard, NFPA 275,replaces references toprevious standards fordetermining an acceptablethermal barrier materialother than 1/2–inch gypsumwallboard.23/32-inch wood structuralpanels satisfy the thermalbarrier requirements forfoam plastic insulation.Copyright 2015 International Code Council2015 IRC Transition from the 2009 IRC552015 Section R322.1 is modified to emphasize thatthe provision applies to existing buildings inflood hazard areas where 50% or more of thestructure has damage and requires restoration.Section R322.2 limits the minimum elevationallowed for dwellings in flood hazard areas anddefines a Coastal A Zone.2015 IRCR316.42015 IRC Transition from the 2009 IRC New provisions allow the installation of structuralinsulated panels and other materials containingfoam plastic insulation as part of a floor systemwithout requiring a thermal barrier on the uppersurface.
